The SN74ALB16244DLG4 is a digital logic buffer, driver, receiver and transceiver. It is part of the Octal Bi-Directional Bus Transceiver series from Texas Instruments. This device is designed to provide the solution to high performance systems that require reliable data transmission and robust power protection.

The SN74ALB16224DLG4 device has 14I/O lines, which are partitioned into two groups of seven lines. Each group has separate two-directional channels and is capable of transferring data independently. It can provide flow control when either or both directions require to be held in one direction. The SN74ALB16224DLG4 device provides high performance and low power dissipation when there are no data transfers.

Working Principle

The devices in the SN74ALB16244DLG4 series operate at the +5V logic level. The dual-directional channels allow the device to interface with multiple systems using various data formats, reducing the need for frame synchronization. The device features an independent driver and receiver on each of the input and output channels, allowing them to transmit and receive data signals without any interference.

The parts of the device have an active-LOW enable/disable control for each direction. When enabled, both drivers are enabled for bidirectional communication and when disabled, data flow stops in both directions. The active-LOW output-enable control is used to disable both drivers when data throughput is not required.

The SN74ALB16224DLG4 device also features power protection circuitry which prevents the output drivers from saturating when they receive high-frequency input signals. This prevents signal shadowing, which can otherwise cause data errors. The power protection circuitry can also help to protect the device from damage due to electrical transients.

Application Field

The SN74ALB16244DLG4 device is ideal for asynchronous bidirectional data transfers in applications such as microcontrollers, data couplers, clock and data multiplexers, data acquisition systems, and switch matrices. Its features make it suitable for a wide range of communication applications, including digital audio, industrial control networks, telecommunications, and home automation.

In addition, the ESD protection circuitry of the SN74ALB16244DLG4 device makes it a reliable choice for applications requiring reliable data transmission over long distances. The device can also be used in safety-critical applications, since it comes with an in-built fault-tolerant design to protect against damage caused by electrical overstress.

The SN74ALB16244DLG4 series of devices from Texas Instruments provide high performance and reliability for data transmission in a wide range of applications. It features an independent driver and receiver on each of the input and output channels, allowing them to transmit and receive data signals without any interference. The SN74ALB16244DLG4 device also features an active-LOW enable/disable control for each direction, as well as power protection circuitry for reliable data transmission.
